| The knowledge of rheological properties of agricultural fruits can be significantlyhelpful in design and fabrication of the appropriateprocessing machines .In this study, the viscoelastic characteristics of date (Mazafati variety) were investigated. Experimental tests were established in six moisture levels (7.5, 9.0, 10.8, 12.8, 17.59 and 25.5 on dry basis) and temperature of 45ºC which contributed to obtain a suitable model. To achieve the desired moisture levels, various saturated salts were used. A chamber capable of controlling temperature was fabricated and placed around the plunger of texture analyzer to monitor the temperature during the experiments. Tests were conducted using an Instron Universal Testing Machine in the way that, samples were... |

| The drying characteristics of green peas during combined hot air-infrared drying were examined. The experiments were carried out for combination of four infrared power intensities (0, 0.2, 0.4 and 0.6 W.cm-2) and three levels of drying air flow rate (0.5, 1 and 1.5 m.s-1) and three levels of drying air temperatures (30, 40 and 50° C). Among several models which were fitted to the experimental data, the Three Term model was introduced to be the most appropriate model to predict moisture ratio as a function of air flow rate, drying air temperature and infrared power density. The statistics indexes of 99.7%, 0.000121, 0.0000 and 0.000121 for R2, X2, MBE and RMSE were obtained for the Three Term model, respectively. Application of infrared radiation in... |
